WATKINSON' LII'III'IED, OF LONDGN, ENGLANIQ'ABRITISH COMPANYVENTILATING-LOUVER roe wnvnows Application filed Fe bruary 26, 1930,Serial No. 431,613, and in Great Britain March 12,1929.

This invention is for improvements in or relating to windows, and'hasfor its object to provide an improved construction of ventilating louverof the kind which is used in conjunction with a sliding window, beingsituated at that end of the path of movement fromwhich the slidingwindow moves when it is being opened. The louverwhichisgenerallysomewhat inclined to the plane of the window, overlaps part ofthe path of .movement of the window so that with a small amount ofopeningof the window, a tortuous path is provided which givesventilation without draught. Windows "fitted with such louvers :arecustomarily used on vehicles, but

it will be appreciated that their use is not thus limited.

'The present invention. comprises a ventilating louver of the kind abovedescribed,

comprising a panel and supporting brackets, whereinithep-anel and itssupporting brackets are independent of one another and so constructedthat the supports can be mounted subsequently detachably secured tothem.

According'to a'further feature of this invention, a ventilating louver.of the type described comprises two brackets which are adapted to besecured on opposite sidesofthe window frame, and which are of open anglesection facing one another to 1 provide sure,

faces on each bracket to engage a'face and an edge ofthe panelrespectivelywhen the panel is laid on the brackets. i

According to another feature of the invention each bracket may beprovided at its outer end with an upstanding lugto constitute anabutment for the outer edge of the panel, with o-rwithout a resilientpacking interposed "between the ipanel and the lug, and with or withoutmeans for maintaining said packing in compression.

When a louver according to the present inventionis-provided with a glasspanel, the upper edge-may bemounted in a metal channel which is securedto the window frame,

and is so positioned as to press the panel against the resilientpacking. aforesaid at the outer end ofithe brackets. f

According to a further featureof the vention, the bracket or the channelis provlded with a recess to accommodate apart of the channel or of thebracket respectively,

invention, there is provided a gutter which extends lengthwise of thepanel- There will now be described with reference to the accompanyingdrawings, a particular, construction of ventilating, louver embody ingthe above-mentioned principal features of the invention, and alsocertain-other novel details, it being understood, however, that thisdescription is given merely by way of an example of the presentinvention.

In the drawings Figure 1 is an elevation of two adjacent louvers mountedon the side of a vehicle'with certain parts broken away, 7

Flgure 2 is a .section through a panel on the line 22of Figure 1,

Figure 3 is asectionthrough a bracket on the line8'3 of Figure 1,

Figure 4 is a perspectiveview of; a bracket,

Flgure 5 is a section similar. toFigure 2 of a modification, and

F'gurefi is an elevation partly in section-- rail 10 and thepillars 11.Thesebrackets, preferably, take the form :of sheet metal stainpings ofsteel, so as to ensureiadequate strength with economyin manufacture.

The bracket 12 which is situated between the two windows isofrectangularchannel section, see especially Figure 4 witha flange l3directed outwardly from each lip of the channel. At the upper end'of thebracket, the depth of the channel is progressivelyv decreased as shownat 14 and the flanges 13 are inclined to the general plane of the bodypart of the channel. The sloping portion 14 of the base of the channelmerges into a portion 15 which lies in the same plane as the inclinedportions of the flanges, and said inclined portions are secured to thecant-rail 10 by screws 16 so that the bracket is inclined outwardlyaway. from the cant-rail at a suitable angle, say 1520, as shown inFigure 3. At the lower end of the bracket, the flanges 13 are extendedbeyond the channel portion and their end portions are turned up at rightanglestothe flanges to form lugs 17. These upturned lugs are about thesame length as the depth of the channel. lVhen this bracket is thusmounted on the cant-rail, the open side of the channel faces the side ofthe vehiole;

A further support for the bracket is provided by a screw 18 passingthrough it near its lower end and screwed into the pillar 11. A distancesleeve 19 surrounds the screw and constitutes an abutment against whichthe bracket is drawn by the screwing in of the said .screw. Preferably,a recess 20 is formed in the base of the channel of such a shape as toengage theliead of the screw 18 squarely when it is screwed in atright-angles to the plane of the pillar 11.

It will be seen that this bracket provides on each side of it a surfaceon the flange 13 on to which a panel 21 is laid, and a surface on theside wall 22 of the channel against which the ed of the panel 21 canabut. Also, the lug 1 provides an abutment for the lower edge of thepanel, and there is provided on this abutment a resilient packing, suchas a block of rubber 23, against which the panel is pressed so as tomaintain the packing in compression. 1 A series of brackets of this typeare provided for the various windows of the vehicle, and at the two endsthe brackets are similar exce t that one flange 13 is omitted. One endbrac et is shown at 24 in Figure 1.

The panels 21 are preferably of sheet glass, and the upper edge of eachsheet is mounted in a metal holder which extends throughout the fullength of the sheet, any suitable packing 25 being interposed as isusual. In the construction shown in Figures 13, the holder is formed intwo separate parts 26, 27. The part 26 is shaped to provide a gutter 28and one limb 29 of a channel to receive the upper edge of the glasspanel and is secured to the cant-rail 10 by screws 43. The other part 27is a metal strlp which is pressed out to provide the other limb 30 ofsaid channel and a.

projection 31 which enters a recess 32 in the part 26. The part 27 ofthe holder is screwed on to the cant-rail 10 by screws 33, and it willbe appreciated that the location of this part determines the location ofthe part 26 and, therefore, of the lower edge of the panel which ispressed against the resilient acking' 23. The part 26 of the channel isof such a length that it overlaps the brackets 12 but the part 27 ismade in separate strips and recesses 34, see especially Figure 4, areprovided in the flanges 13 of the brackets to accommodate the parts ofthe ends of said strips which lie in the same plane as the portion 15 ofthe bracket. These recesses serve to locate the holder and the panel inthe desired position on the bracket when assembling the Whole device. Itwill be seen that interlocking engagement is provided between thebracket and the holder and also between the two parts of the holder.Further after the brackets have been mounted in place the panel can bevery easily inserted in them and, moreover,it can be readily detachedand replaced as is sometimes required in the case of a glass panel beingbroken.

In order to secure the panel in position and to enhance the appearanceof the whole device, cover-plates 35 which may be nickelplated orotherwise made of pleasin ap earance, can be secured to each brac keth'a pair of screws 36 engaging the bracket. y convenient locking meansmay be provided at the back of the base of the channel-porti on of thebracket, such as a locking-plate 37 the upper edge of which is held inplace by a lip 38 depressed out of the channel. The cover-plates 35 maybe in the form of flat plates, in the case of double-sided brackets,although preferably they are provided with an overhanging lip 39 toconceal the lower end of the bracket. Similarly, the coverplate for anend bracket, such as 24, may be provided with a side wall of triangularshape, as shown at 40 in Figure 6 and hereinafter referred to, toconceal the side of the bracket and close thegap between the bracket andthe pillar 11.

Strips of packing 41 are arranged alon the side edges of the panel 21,and between t ese stri s and the strip 25 corner pieces 42 of pacin'g'are provided. In Figure 1, the packing is shown as projectingbeyond the coverplates 35. This has been done in order to show thepacking clearly; generally the packing will be concealed.

In the modification illustrated in Figure 5, the upper end of the panelis received in a metal channel 44 which is made in one piece comprisingthe gutter 28 and the two limbs 29, 30. This channel is secured to thecantrail 10 by screws similarly to'the part 26 of the two-part channelillustrated in Figures 1-3, and it will be appreciated that suitablyshaped recesses are provided in its rear Wall to accommodate the upperends of the brackets. I

Figure 6 shows a device according to the invention applied to a door 45of a vehicle. In this construction, the brackets 12 i are shaped andfixed in position as hereinbefore described with reference to Figures 14, and the upper end of the panel is mounted in a metal channel. Thepanel is held in position by a cover-plate which, is of ornamental ciseconstructional details described as they can be varied without departingfrom the in-' vention as defined'by the appended claims.
